Study on Physiological and Biochemical Effect of Prometrgne on Ziziphus jujuba

This trial studied the effects of prometrgne on the young shoot growth,leaf chlorophyll content,MDA content and electrical conductivity of membrane of Ziziphus jujuba Mill.The results showed: prometrgne had obvious effects on the growth of Ziziphus jujuba Mill.In short time,The higher the concentration was,the greater the effects would become,but after sparying for 20 days,the influence become almost disappeared.The results can be concluded that: when we use the chemical-herbicide prometrgne in the Ziziphus jujuba Mill.nursery garden or in the intercropping field,the concentration below 2g/kg is safe.
